2014 Ram Heavy Duty spy shot

Ram is readying a facelift for its heavy-duty truck lineup, and KGP just caught a revamped 2014 Ram 3500 Dualie prototype testing on public roads.

Expect a diesel power boost to 800 lb-ft with capacity boosts for both diesel and gas engines. Reliable source Dom said that there would be a 6.4 Hemi option for the Ram heavy duty trucks, along with a new transmission to compete with the GM’s Allisons. (We expect an Aisin, which Dodge already uses.)

Heavy duty Ram pickups will be getting an optional air suspension setup, according to several sources. The Long Hauler concept used a Kelderman air suspension in front and rear, for higher capacity with a smoother ride; that model was based on the Ram 5500, which has a leaf-spring rear suspension. The Long Hauler now appears to be a “go” for production.
